Narva Sealed Rocker Switch Off/on Spst 12V/24V Blue LED 20A 63159BL

The Narva 63159BL is a sealed rocker switch with Off/On SPST operation, a blue LED indicator, and a current rating of 20A at 12V or 10A at 24V. It is listed as a 5-terminal switch with push-on terminals and a mounting opening of 37.5mm x 21mm, so it suits applications where the cut-out size and wiring style need to be checked before purchase.

This switch is designed as an illuminated rocker with both ‘Dash Light’ and ‘On’ illumination. That makes it suitable for setups where you want the switch state to be visible at a glance, while still keeping the fitment decision tied to the physical opening size, terminal layout, and the electrical load you intend to control.

With a mount length of 37.5mm and a listed weight of 0.04kg, this Narva switch is compact and purpose-built for 12V and 24V electrical systems. The product is supplied as a single each item and carries a one year warranty.

Because this is a SPST switch with 2 positions and 1 pole, it is important to match the intended function to the circuit you are wiring. The 20A rating at 12V and 10A at 24V are the key figures to check against the accessory or circuit load before installation.

Application and Buying Notes

Before buying, confirm the panel cut-out matches the listed mounting opening of 37.5mm x 21mm. That is the most practical first check for a rocker switch like this, because the switch can only be fitted properly if the opening size and shape suit the dash, console, or custom panel you are working with.

Next, check the electrical side of the job. The switch is rated at 20A at 12V and 10A at 24V, so the connected circuit should stay within those limits. If the circuit load is higher than the switch rating, it should not be used for that application.

The switch uses 5 terminals with push-on terminals, so wiring style matters as much as physical size. Make sure the vehicle or accessory wiring can be matched to that terminal arrangement before ordering, especially if you are replacing an existing switch rather than starting from scratch.

The illuminated design includes both ‘Dash Light’ and ‘On’ illumination, which is useful where switch visibility is important. Even so, lighting style alone does not confirm compatibility, so the correct part number, 63159BL, and the measured opening size should be used as your main reference points.

As a sealed rocker switch, this unit is intended for installations where a more protected switch body is preferred. That still does not replace a proper application check, because rocker shape, terminal count, and voltage rating all need to suit the job as well as the physical space available.

If you are unsure whether this is the right switch for your setup, compare the old switch or the intended panel cut-out against the 37.5mm x 21mm mounting opening and verify the circuit voltage is 12V or 24V. Taking those checks before purchase is the safest way to avoid a mismatch.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 63159BL helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Relevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 20, Voltage 12, Mount Length 37.5mm, Number of Positions 2, Item Type Switch, Weight 0.04kg, Product Group 1 AUTO ELEC ACCESSORIES.

Additional published details for cross-checking include Part No. 63159BL, Brand NARVA, Description Narva Sealed Rocker Switch Off/On SPST 12V/24V Blue LED (Contacts Rated 20A @ 12V), Number of Terminals 5, Switch Action Off - On - SPST, Lamp Colour/s Blue, Number of Poles 1, Switch Type Rocker, Switch Illumination Illuminated.

Narva Sealed Rocker Switch Off/On SPST 12V/24V Blue LED (Contacts Rated 20A @ 12V). Part number 63159BL should be checked first. Listed voltage is 12. Listed output rating is 20. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 63159BL, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 20 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using part number 63159BL, the 37.5mm x 21mm mounting opening, the 5-terminal push-on layout, and the 12V/24V electrical rating before ordering.
